Breastfeeding?

I like it and I'm glad I can do it this time. But I just don't enjoy it (not as bad as last time thank god). But I get anxious sitting for so long and not really getting to move around while feeding (I can do it one handed and stuff but I still feel very uncomfortable almost). He latches great and eats great and I'm producing. I feel guilty because I just really don't want too. I know "breast is best" and I fully wish I enjoyed it like I should. My mom makes me feel shitty for supplementing (he had jaundice and needed lots of food and I didn't produce yet). I just need to know I'm not alone.
